2010-04-10 Thread Reid Kleckner
Hey folks, I was looking at tuning Python dicts for a data structures class final project. I've looked through Object/dictnotes.txt, and obviously there's already a large body of work on this topic. My idea was to alter dict collision resolution as described in the hopscotch hashing paper[1].
